Background: Necrotic enteritis (NE) is a severe intestinal infection that affects both humans and poultry. It is caused by the bacterium Clostridium perfringens (CP), but the precise mechanisms underlying the disease pathogenesis remain elusive. This study aims to develop an NE broiler chicken model, explore the impact of the microbiome on NE pathogenesis, and study the virulence of CP isolates with different toxin gene combinations.

Background: Expedient access to early intervention (EI) systems has been identified as a priority for children with developmental delays, identified disabilities, and other special health care needs. Despite the mandated availability of EI, it remains challenging for families to navigate referral processes and establish appropriate services. Such challenges disproportionately affect families from traditionally underserved communities.

This article critically reviews techniques and theories relevant to the emerging field of "lie detection by inducing cognitive load selectively on liars." To help these techniques benefit from past mistakes, we start with a summary of the polygraph-based Controlled Question Technique (CQT) and the major criticisms of it made by the National Research Council (2003), including that it not based on a validated theory and administration procedures have not been standardized. Lessons from the more successful Guilty Knowledge Test are also considered.

Synopsis of recent research by authors named "Alexa Dixon"

  • - Alexa Dixon's recent research spans diverse fields, focusing on the role of the microbiome in necrotic enteritis in poultry, the development of an app to enhance family engagement in early intervention services for children with developmental challenges, and improving lie detection techniques through cognitive load theory.
  • - In her study on necrotic enteritis, Dixon examines the impact of jejunal microbiome composition on disease progression in a broiler chicken model while investigating the virulence of different Clostridium perfringens isolates.
  • - The development of an app for tracking family engagement highlights the barriers faced by underserved communities in accessing early intervention services, aiming to streamline referral processes and improve support for children with identified needs.
